Wipro — Upload option is not enable

Hi sir/madam.
My name is surya and resume is 24107940. I got offer letter on March 21st 2022. As per the instructions given I had uploaded all my documents in ICIMS portal. After some days I got mail that to upload my final marksheets .
In that portal it is mentioned to clear and reupload all the documents according to that I had cleared the previous documents. But the upload option is not enable that is why I cannot upload any documents.
For past 6months I am raising a complaints against this issue to Wipro helpdesk but they are not responding properly. So please solve this issue.

Thank you
K.Surya
